This Bluetooth Laser Mouse is an excellent tool for medical offices, libraries, and schools as well as for mobile professionals, gamers, and desktop users. This mouse uses VCSEL (Vertical Cavity Surface Emitting Laser) as the light source, which provides 30x more tracking power than mice using an optical sensor. Works on virtually any surface, delivering an extremely high resolution of 1600 dpi, substantially reducing the amount of injury-producing hand and arm movement. It is USB ready, Plug-n-Play, and Hot Pluggable and offers a 33 feet (10 meter) wireless range.
